华侨城大厦东翘首悬挑钢结构无支撑安装施工技术

Installation Technology Without Bace of East Cantilever Steel Structure in OCT Building

主要介绍华侨城大厦东翘首悬挑钢结构,创新性地采用斜拉杆无临时支撑的施工方法,根据本工程结构特点,确定安装顺序,通过建立模拟计算模型与安装实例,说明了该施工方法的可行性,改变了原来悬挑结构吊装时增设胎架临时支撑的安装方法。采取了无支撑安装施工技术后,施工效率得到了较大提高,减少了安装难度的同时也取得了较好的经济效益。

This paper mainly introduces the construction method of the east suspension cantilever steel structure of the OCT Building without temporary brace,which confirms the installation sequence according to the structural characteristics of this project. Besides,the feasibilities of the construction method are explained and the installation method of original cantilevered structure hoisting that additional framing as temporary brace is changed by establishing the simulation calculation model and installation cases. Without the brace to install the construction,the construction efficiency has been greatly improved,reducing the difficulty of installation and also achieved better economic benefits.
